Rain Lock is a jailbreak tweak that lets you add custom “rain” effects to the iPhone’s Lock screen. The rain is really just text, which can be custom text or one of the two built-in text effects.

As you may have already figured out, Rain Lock isn’t the type of tweak that adds enhanced functionality to your iPhone, neither does it help you work smarter—it’s a tweak that’s unapologetically centered on visual flair. And that’s okay, because that’s what Rain Lock does well, and it gets it right for the most part. Mosey on inside for a look into how Rain Lock works via our hands-on video walkthrough…

As with most tweaks with customizable aspects, you’ll need to go into the stock Settings app to find Rain Lock’s preferences. The preferences for Rain Lock is its weakest point. There’s just too many settings and not enough cohesiveness. I wish developers focused more on polishing the back-end aspects of their releases, as doing this would make for an easier and more pleasurable experience when it comes to configuration.

Rain Lock 05

Rain Lock defaults to the typical Matrix-inspired text with the green and white abstract letters, but you can customize it with text of your choosing, and even alter the color of the text. The color customization allows you to select a head and tail color, which, as I quickly realized, works best on longer text strings.

Rain Lock 03

Invoking RainLock can be accomplished by using a simple double-tap gesture on the Lock screen or a short press. You can also enable a toggle in the tweak’s preferences to make the rain effects auto start upon locking your device.

Lastly, you’ll find settings for a custom intro message i.e. “wake up Neo,” rain size, rain speed, and rain amount. I think it’s pretty safe to say that with a few minutes of customization, you’ll be able to come up with a look that’s wholly original and unlike anyone else’s Lock screen.

The privilege to use Rain Lock will cost you a bit more than the average tweak, though; it’s priced at $2.50 and it’s available right now on Cydia’s BigBoss repo. The price might be a hard pill to swallow (see what I did there?) due to the fact that the tweak adds no functionality improvements to iOS, but if you’re at all concerned about having an original looking Lock screen, then you’d be hard pressed to come up with something better than this. What do you think?

    cool cool. battery life?

    • Javier

      No affect on battery life as it is only activated when lockscreen visible, deactivated when it’s not.

    This is one of those tweaks which you install, just to show off in front of your friends and then deinstall it after approximately one week ! haha

      Got this tweak a while back… Still using it. Than again, I like animation type tweaks, like barrel, unfold (even though its not iOS7 anymore), dock&roll, etc.


    my friend installed this tweak he was newly restored and jailbreaked his iphone so really pure phone, installed this tweak.. and tada it made his device on an unbootable mode. i highly doubt that from a “tweak” but just sayin

    • Eni

      i don’t think he restored and rejailbreaked again thought, coz 7.1 it cant be jailbroken


        this tweak was on cydia for a while, it’s not new

  • Tom

    It’s actually Japanese. Not Matrix.

    • Javier

      “Katakana” to be precise, which is what most of the characters consisted of in the matrix series.

      • Paul

        Pretty close to original but they are not mirrored (flipped) Katakana

  • Walcy Carroll

    vwallpaper2 is better

    • Paul

      Except it’s not because it’s video which takes up a lot of space and kills battery.

      • Walcy Carroll

        true good point, i recently killed just about anything that does overkill drainage on my battery
